cmiVFX Vue Moving Matte Paintings(VUE教程).cmiVFX launches its latest Full Feature training video in E-on’s premiere digital environment generation tools names Vue. Whether your in the need for a digital back drop or detailed environment, Vue’s highly capable solution is right for you. The cmiVFX users have been requesting this training video for quite some time, and we agreed that the majority of both CG artists and VFX artists should have this knowledge for better completing their pieces of work. Never before have we felt so strongly about every artist watching one of our videos before now. This video is a MUST SEE. Compositors will use it for sky replacements and element fill. CG generalists will uses it for the construct for the majority of their scenes. Vue is highly compatible with most animation packages, so getting data back and forth is only a few clicks away..Chapter 01 – DEMA digital elevation model (DEM) is a digital representation of ground surface topography or terrain. It is also widely known as a digital terrain model (DTM). A DEM can be represented as a raster (a grid of squares, also known as a height map when representing elevation) or as a triangular irregular network. DEMs are commonly built using remote sensing techniques, but they may also be built from land surveying. DEMs are used often in geographic information systems, and are the most common basis for digitally-produced relief maps. In order to build a terrain based on a real location we need to find the elevation data first. We are going to find the data online, convert it to a Vue friendly format and import it into vue to start working. We will go over a couple of different ways of doing it..Chapter 02 – Framing and LightingLighting in Computer Graphics refers to the placement of lights in a scene to achieve some desired effect. Vue and other animation packages all contain different types of lights that can be placed in different locations and modified by changing the parameters. Too often, people who are creating images or animations ignore or place little emphasis on lighting. This is unfortunate since lighting is a very important part of image synthesis. The proper use of lights in a scene is one of the things that differentiates the talented CG people from the untalented. This is not a new topic as a large amount of work has been done on lighting issues in photography, film, and video. Because we will be working with a terrain which can’t be changed of moved, we will do what photographers do. We will find the best angle and frame for the scene with the camera alone. Then we will “wait” for the right light (by moving the sun around) to get the perfect light for our landscape..Chapter 03 – MaterialsMany real life surfaces are not just colored but also have textures and patterns. Many also have small or large surface displacements or bumps, gouges, etc. Texture mappin
